EASA AD 2024-0021
SUPERSEDED BY EASA AD 2024-0076
Summary
EASA Airworthiness Directive 2024-0021 is issued for Dassault Aviation Falcon 7X aeroplanes, including those modified as Falcon 8X in production. It mandates inspection of specific ailerons with certain part numbers and serial numbers due to potential excessive trailing edge thickness that could compromise structural integrity. The directive provides detailed inspection and corrective action instructions based on Dassault Service Bulletins 7X-593 Revision 1 and 7X-594.
What Changed
This new airworthiness directive introduces a one-time inspection requirement for affected ailerons on Falcon 7X and Falcon 8X aircraft to detect and address excessive trailing edge thickness. It also prohibits installation of affected ailerons after the effective date and requires corrective actions if discrepancies are found during inspections. The directive does not supersede any previous ADs.
Why It Matters
This directive is critical for maintaining the structural integrity of the ailerons on Falcon 7X and Falcon 8X aircraft, directly impacting flight safety. Operators, maintenance organizations, and compliance teams must ensure inspections and repairs are performed within specified flight cycle limits to avoid unsafe conditions. Non-compliance could lead to grounding of aircraft or regulatory penalties.
What To Do
Operators must inspect affected ailerons before they exceed 8,000 flight cycles for Group 1 parts and 4,000 flight cycles for Group 2 parts, following the instructions in Dassault Service Bulletins 7X-593 Revision 1 and 7X-594. Any discrepancies found must be corrected before the next flight, including contacting Dassault if required. Additionally, no affected ailerons may be installed on any Falcon 7X or Falcon 8X aircraft from 31 January 2024 onward.
